Use 12-Volt Portable Solar Panels To Create Usable Energy

One of the most popular types of portable solar panel systems is the 12 volt (12v) format.

But just how much energy does 12v give you? Not enough to warm up your house, but enough to run some of your portable devices, or recharge their rechargeable batteries.

These portable panels operate like large solar panels, but generate less electricity due to their smaller size. Like their larger cousins, they function best under direct full sun conditions. They still work on cloudy and even rainy days, however, they will take a much longer time to generate the electricity to power your device. Most will not operate with indoor lighting, but there are solar panels being developed that will be able to use indoor light. Some have already reached the consumer market.

Great portable panel systems have built-in regulators, meaning they’ll mechanically correct the amount of energy they make to the amount that the device requires. So be sure that the portable panels you buy have this feature, otherwise there’s a risk of overcharging (or “frying”) the contraption that you’re trying to recharge.

You still need to be careful when handling portable solar panels, it’s not like you can go swimming with them. If you fold or crease the solar cell itself, you’ll probably fracture or disable it. So don’t fold the cell, or put the portable panels in the washing machine, or stab them with knifelike objects. A weight belt can survive a fair amount of abuse, but your portable solar panel will be out of luck.

One more word of caution: the portable solar panel can’t reload regular batteries. It can only charge rechargeable batteries. This may be obvious to you, but you’d be surprised how many people try to recharge ordinary batteries.

You will need additional connector equipment in order to use the portable panels, so plan for the additional expense. You’ll need connectors that fit with the recharging plugs on your portable devices. And if you plan to use your portable solar panels to trickle charge your car, boat or snowmobile battery, you might need a set of battery clips.

“Trickle charging” can keep your vehicle’s battery completely charged. Here’s how it works: place the portable solar panel on a surface where it receives the most sun; then plug it into the cigarette lighter socket, or attach the clips to the vehicle’s battery. This can be a great help in really cold climates where temperatures drop below freezing, and you have to keep your car parked outside all day.

Portable solar panels are still relatively expensive compared to using grid electricity at home or in the office. But they make sense if you spend a lot of time camping, hiking or working from your car. And they’re great backup systems for times when the power goes out.
